CLOSE UP OF TAX STAMP
U.S. Revenue Proprietary. Scott catalog number RB11.-----------------------------------------
This is what Eric Jackson, revenue stamp expert says about this Little Brown Jug..."This stamp is a proprietary stamp that was in use from 1875-1881. The jug probably contained something that was medicinal in nature, probably a patent medicine or bitters, that was subject to the tax. It is a common stamp, but it is nice to find the usage on the jug.
Regards, Eric Jackson."
